And if the shaft is touching a metal box, another electrical part, or your finger, bad stuff can happen.
Can I touch a live wire?
If you are in contact with a live wire or any live component of an energized electrical device—and also in contact with any grounded object—you will receive a shock. You can even receive a shock when you are not in contact with an electrical ground. Contact with both live wires of a 240-volt cable will deliver a shock.
Can a live wire kill you?
